Which register pair is known as memory?
H and L register pair is used to act as memory pointer and it holds 16 bit address of memory location.
Which register pair of 8085 microprocessor is used as memory pointer?
stack pointer
The stack pointer is also a 16-bit register used as a memory pointer. It points to a memory location in R/W memory, called the stack. The beginning of the stack is defined by loading 16- bit address in the stack pointer. The instructions MOV B, A or MVI A, 82H are to copy data from a source into a destination.
What is the memory in 8085?
The memory capacity is 64 KB. Also 8085 Can Perform Operation Upto 2^8 ie. 256 numbers. A number greater than this is to taken multiple times in 8 bit data bus.
Which register pair of 8085 is used to store the memory address for memory related instructions?
Program counter It is a 16-bit register used to store the memory address location of the next instruction to be executed.
Which of the following are the register pair in the 8085 microprocessor?
The 8085 has six general-purpose registers to store 8-bit data; these are identified as- B, C, D, E, H, and L. These can be combined as register pairs – BC, DE, and HL, to perform some 16-bit operation. These registers are used to store or copy temporary data, by using instructions, during the execution of the program.

What is the use of memory pointer?
A memory pointer (or just pointer) is a primitive, the value of which is intended to be used as a memory address; it is said that a pointer points to a memory address. It is also said that a pointer points to a datum [in memory] when the pointer’s value is the datum’s memory address.
Which pin of 8086 is used for memory interfacing?
It is available at pin 28. It stands for write signal and is available at pin 29. It is used to write the data into the memory or the output device depending on the status of M/IO signal.
Which register is used to point to the memory address from which the next byte is to be fetched?
Program Counter
Program Counter This register is used to sequence the execution of the instructions. The function of the program counter is to point to the memory address from which the next byte is to be fetched.
What do you mean by registers in memory write name of all registers with their bit size?
Address Register: It is a 12-bit register that stores the address of a memory location where instructions or data is stored in the memory. I/O Address Register: Its job is to specify the address of a particular I/O device. I/O Buffer Register: Its job is to exchange the data between an I/O module and the CPU.
Which register pair is used by 8085 internally for execution of Xchg instruction?
In 8085 Instruction set, there is one mnemonic XCHG, which stands for eXCHanGe. This is an instruction to exchange contents of HL register pair with DE register pair. This instruction uses implied addressing mode. As it is1-Byte instruction, so It occupies only 1-Byte in the memory.
